Applicatiqn filed April 1,

arms attached to railway car trucks below the brake beams of brake gears for supporting V the beams in case their supporting brake '6 hangers or other connections fail. 1

The object is to provide a simple and effective means for supporting a safety arm in such manner that it is continuously held in its operative position, the connecting means being so formed that a. safety arm may be quickly and easily attached to and re moved from a truck.

The invention is illustrated in the'accompanying drawings, of which Fig. 1 is a com- 1 bined transverse'sectional View of a spring plank ofa railway car truck and a side elevation of a safety arm showing it attached to the spring plank; .Fig. 2 a view corresponding toFig. 1 showing the arm-attaching means moved to a position for applying the safety arm to or removing it from a truck; and Fig. 3 a view taken on the plane indicated by the line III-III, Fig. 1.

According to thls lnventlon, a brake beam guard bar or arm is attached to a spring plank of a railway car truck by means of a resilient bracket connected to the spring plank and provided with an opening to re ceiving and supporting the bar, the bracket being so formed that it yieldingly engages the bar to normally look it in operative position. Preferably, the spring plank or an equivalent supporting member of a railway car truck is provided with two brackets for recelvlng and supporting a guard bar, one belng formed for locking the bar in the manner just explained, and the other being formed to ,merely receive and support the f guard bar, means being attached to the bar 40 for engaging the said other bracket to pre vent longitudinal vmovement of the bar. However, if desired, both of the brackets may be formed of resilient spring metal and shaped to yieldingly engage the bottom of a guard bar to lock it in operative position.

Having reference to the illustrative embodiment of the invention, a spring plank 1 of the railway car truck is shown as having attached to it two'brackets 2 and 3, eachprovld-ed with a slot for receiving a guard BRAKE BEAM GUARD ARM f:

' 193( j Serial: no, 446,745, v I q bar 4, which is preferably inlthe' formof a simple plate of suitable depth and thickness for-Hits intended purpose.v "Vvhileithese brackets may b e" fvariouslyattached to the sprin'gfplank, they are illustrated as being connected'to' it byrivets 5. Bracket 2, which in" this embodiment of the invention locks the guard bar fin operative position, i is formed of-'resil ient spring metal with its lower end turned laterally and upwardl'y so that it yi'eldingly engages'the bottom of bar 7 l to lock it in position.'- Preferably, the

lower edge of'the bar is provided with a plurality of notches 6 for engagement by the upper e ge Of the slot formed in the bracket. V

WVhen bare is removed from the bracket, thelower'end of'the bracket, being unstressed, lies in. the position indicated in dottedjlincs ,in-Figi1,-*-" I To apply a barA to bracket 2,thelower=end L of the bracket is flexed downwardly while the end ofathe bar 'is'slipped through" thefbar receiving slot of thebracket. "This may be done by"inserting-asuitable to L-such'as a bar 8,"illustratedin'Figi 2, in a suitableo'pening' 9 (Fig. '8) infthelower end of the bracket, andturningthe outer end of the ba'r' downwardly to the position shown inFig. 2; The right end of bar4,as viewed in Figs l andQ, "may" then be slipped throughthe sllotin bracket 3 from left to right,- and through-the or corresponding slot" or openingin the down wardly'turn'ed end of bracket 2, When arm lie in' its operative position," the downward ,pressureonthe'lower endofbracket'Q is 'released to permitsuchend to; spring upwardly to yieldinglylengage the bottom of thesupportingarm and lock ltfllPPOSltlOH. To resi'st any tendency of supporting arm lniov ing' from left to right beyond its operative' 'positiomqsu'chlbar is preferably provided with rivet or othersuitable projection 10 which abuts against theface of b'racket3 whenfarin 4 is in it's operative position. I By the mean's'provided according to this 1 o invention, a safety arm may be quickly and easily'attached to or removed from a truck, and when connected tothe truck it is securely held in position. 5

According to the provisions of the patent statutes, I have explained the principle and operation of my invention, and have illustrated and described what I now consider to represent its best embodiment. However, I 5 desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as illus trated and described.

I claim as my invention V 1. In a railway car truck, a spring plank, a brake beam guard bar below the spring plank, and a resilient bracket attached to said spring plank and provided with an opening for receiving and supporting said bar, said bracket yieldingly engaging said bar to normally lock it in operative position.

'2. In a railway car truck, a spring plank, a brake beam guard bar below the spring plank, and a resilient bracket attached to said spring plank and provided with an opening for receiving and supporting said bar, the lower end of said bracketbeing turned upwardly to yieldingly engage the bottom of said bar to normally look it in operative position, the bar being released from the bracket by springing the lower end of the latter downwardly.

3. In a railway car truck, a spring plank, a brake beam guard bar below the spring plank and provided with a notch on itslower face, and a bracket formed of resilient spring metal attached to said spring plank and provided with an opening for receiving and supporting said bar, the lower end of said bracket being turned upwardly to yieldingly engage said bar notch. 1

4. In a railway car truck, a spring plank, a brake beam guard barbelow the spring plank, and a pair of brackets attached to the 40 opposite sides of the spring plank and provided with openings for receiving and supporting said bar, one of said brackets being formed of resilient spring metal and having its lower end turned upwardly to yieldingly engage the bottom of said bar to lock it in operative position.

5. In a railway car truck, a spring plank, a brake beam guard bar below the spring plank, a pair of brackets attached to the opposite sides of the spring plank and provided with openings for receiving and supporting said i bar, one of said brackets being formed of resilient spring metal and having its lower end turned upwardly to yieldingly engage the bottom of said bar to lock it in operative po sition, and means attached to said bar for engaging the other of said brackets to prevent longitudinal movement of the bar.

In testimony whereof, I sign my name;

BRODERICK HASKELL.
